The solvent and melt methods were employed to prepare solid dispersions with various water soluble carriers and a slightly soluble drug, sulfabenzamide. The carriers investigated included citric acid, succinic acid, dextrose, polyethylene glycol 6000

Furosemide, a potent diuretic, has been found to give a low bioavailability profile when administered orally which potentially could be due to hydrolysis of the drug prior to absorption. An in vitro kinetic study was performed to elucidate the kineti

The hydrolysis of nitrazepam involves a two-step sequential mechanism. The intermediate is the ring-opened compound resulting from scission of the azomethine bond. The final products are glycine and 2-amino-5-ni-robenzophenone. Recyclization of the i

Erythromycin forms association complexes with four sulfonic acid dyes that can be extracted into chloroform and quantified by spectrophotometry. Of the dyes studied, MO and O IV form 1:1 complexes with the conjugate acid of erythromycin. Solutions co

Differential absorbance spectroscopy was successfully used to follow the hydrolysis kinetics of chlordiazepoxide and demoxepam from pH 1 to 11. Loss of the methylamino group from chlordiazepoxide produced demoxepam. Demoxepam degraded by a parallel c

A sensitive procedure has been developed for analysis of solutions of the macrolide antibiotic, erythromycin. The method is based on ion-pair formation of the conjugate acid of the drug with an 35 S-labeled isostere of methyl orange, partitioning int

A sensitive and selective method for the determination of erythromycin in human blood serum, in the range of 0.1 to 1.0 μg/ml, is described. The procedure is based on extraction of drug into ether and competitive displacement of [14C]-erythromycin f

Sterigmatocystin, a secondary fungal metabolite, produces a toxic reaction upon administration to experimental animals. Examination of rats that have received multiple doses of 14C-sterigmatocystin may indicate the response elicited by repeated expos
